We divide 11266599 by 999
The aim is to understand the frequency of 999 in 11266599.

Advancing to step 1:
1 divided by 999 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 999

Advancing to step 2:
999 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 999

Advancing to step 3:
112 divided by 999 is 0 with a remainder of 112.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 112 leaves us with 112.
Bring next digit (6) of the dividend behind the 112 and repeat the process: 1126 / 999

On to step 4:
If we divide 1126 by 999, we get 1 and a remainder of 127.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 999 from 1126 and we're left with 127.
Append the next digit (6) from the dividend to 127 and continue with: 1276 / 999

Let's proceed to step 5:
999 can be fit into 1276 1 times, resulting in a remainder of 277.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 999 from 1276, we get 277.
Fetch the next digit (5) from the dividend, attach it to 277 and continue: 2775 / 999

Let's proceed to step 6:
999 goes into 2775 2 times with a remainder of 777.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we subtract 1998 from 2775, we get 777.
Bring next digit (9) of the dividend behind the 777 and repeat the process: 7779 / 999

Moving on to step 7:
999 can be fit into 7779 7 times, resulting in a remainder of 786.
Use 7 as the next digit of our solution. 
Result so far: 1127.0
If we subtract 6993 from 7779, we get 786.
Bring next digit (9) of the dividend behind the 786 and repeat the process: 7869 / 999

Moving on to step 8:
If we divide 7869 by 999, we get 7 and a remainder of 876.
Record the quotient 7 as the next digit in the result. 
Result so far: 11277.0
Subtract 6993 from 7869 to get 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

On to step 9:
999 goes into 8760 8 times with a remainder of 768.
The number 8 becomes the next digit in our result. 
Result so far: 11277.8
If we take 7992 away from 8760, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Let's proceed to step 10:
999 goes into 7680 7 times with a remainder of 687.
Write down 7 as next digit of the result. 
Result so far: 11277.87
Deduct 6993 from 7680 and we're left with 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Step 11:
When dividing 6870 by 999, we get 6 with a remainder of 876.
Put 6 as the next digit of the answer. 
Result so far: 11277.876
If we take 5994 away from 6870, we end up with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Moving on to step 12:
8760 divided by 999 is 8 with a remainder of 768.
Put 8 as the next digit of the answer. 
Result so far: 11277.8768
If we take 7992 away from 8760, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Step 13:
If we divide 7680 by 999, we get 7 and a remainder of 687.
Put 7 as the next digit of the answer. 
Result so far: 11277.87687
Subtract 6993 from 7680 to get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Advancing to step 14:
6870 divided by 999 is 6 with a remainder of 876.
Write down 6 as next digit of the result. 
Result so far: 11277.876876
Subtracting 5994 from 6870 leaves us with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

On to step 15:
If we divide 8760 by 999, we get 8 and a remainder of 768.
Write down 8 as next digit of the result. 
Result so far: 11277.8768768
Deduct 7992 from 8760 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Step 16:
The number 999 fits into 7680 7 times, leaving a remainder of 687.
The next digit of our result is 7. 
Result so far: 11277.87687687
If we subtract 6993 from 7680, we get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Our division results in 11277.87687687 with a remaining 6.87e-07.
